Freq' N Lightshow
Items that appear within this website are available for purchase from CableTrak, LLC.
This product is a real-time audio-reactive DMX lighting controller designed to transform music or audio signals into dynamic, synchronized light shows for studios and stages. By utilizing multiple MSGEQ7 seven-band graphic equalizer IC's, it analyzes incoming audio and converts specific frequency amplitudes into DMX signal data to control DMX-compatible lighting fixtures.
Freq'' N Lightshow accepts a 3-pin male connector.
This is a specialized product including a custom ABS enclosure, silk screening and custom software.
1. Unique Control (14 Channels)
With two MSGEQ7 chips, you have 14 distinct data streams representing different audio frequencies. In a standard setup:
Unique Fixtures: You can control 14 fixtures independently if each uses one DMX channel (e.g., 14 single-color dimmers).
Multichannel Fixtures: If you use RGB fixtures (which require 3 channels each), you might only be able to drive 4 complete fixtures uniquely
(14/3) with some bands left over.
2. Grouped Control (Unlimited Fixtures)
Because DMX is a broadcast protocol, you can set an unlimited number of physical lights to the same DMX address through your selected DMX lighting fixture.
Broadcast Limit: You can have dozens of lights behaving identically. For example, if you map the "Bass" band to DMX Address 1, you can have 50 lights all set to Address 1, and they will all pulse together to that frequency.
Physical Chain Limit: A single DMX daisy-chain is technically limited to 32 physical devices before requiring a DMX splitter or repeater to maintain signal integrity.
Summary of Limits
Control Method Maximum Capacity
Unique Frequencies 14 bands (7 per chip)
Standard DMX Chain 32 physical devices per run
DMX Universe 512 total channels
Key Features and Functional Description:
Seven-Band Frequency Analysis: The product uses Qty. 2 of the MSGEQ7 chips to divide the audio spectrum into seven distinct bands: 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz, and 16kHz., yielding 14 channels of colorful frequencies producing stereo signals to be sent to your DMX lighting fixture.
Audio-to-DMX Mapping: The analog DC voltages generated by the MSGEQ7 for each band are processed by a microcontroller to create DMX channel values (0-255).
Dynamic Lighting Effects:
Bass Response (63Hz, 160Hz): Triggers strobe lights, strobing pars, or intense dimmer effects.
Mid-Range (400Hz, 1kHz, 2.5kHz): Controls color changes, moving head positions, or pattern changes based on vocals or instruments.
Highs (6.25kHz, 16kHz): Triggers high-frequency shimmers, fast chases, or bright white flashes.
Live Synchronization: Enables studio/stage lights to "pump" or pulse in real-time with the music beat.
Adjustable Sensitivity: Includes a pre-amp circuit to adjust input audio amplitude, ensuring optimal performance for quiet or loud environments.
A system with two MSGEQ7 chips provides 14 unique frequency bands (7 per chip), which typically allows you to control 14 individual light groups or fixtures if each is mapped to a single frequency band.
However, the actual number of physical fixtures you can run depends on your control method and how you address them.
This system is ideal for creating automated, music-driven light shows without requiring a manual lighting operator.
DMX LIGHTING FIXTURES NOT INCLUDED.
DMX Output: Sends a standard DMX-512 protocol signal, making it compatible with industry-standard stage lighting systems, dimmers, and LED fixtures.
